Level 3 scratch built

I got my level 1 on a kit and I'm attempting my level 2 at Thunderstruck this year so I've started designing my level 3 cert rocket.

Could someone please review it and comment.

I don't use Open Rocket so I can't see it I've been useing vcp from the 1.5 release and still use 1.64 even though Gary hasn't updated it in ages. A stone age program for a stone age man

Have you found your TAP advisors? They should be able to help you out with any problems.

Cyborg,

It sounds like you are motivated to cert level 3. I definitely agree with Dave Carver that you need to connect with TAP people for advice. They will walk you through the process. Good luck and enjoy the journey.

Quick 2 things I would comment on, I only looked briefly.

It is a nice design and inherently a good one. First , I see the fin can is 36 in. long, you will generally find glass tubing comes in 48in and above sizes. Might want to consider a longer fin can using a full [48] tube. Actually many 4in. rockets today use 50-52 in tubes. There are many M-motors over 40in long. Since you are going to all this trouble to build your rocket, why limit what you can fly it on.

You may have ulterior motives , that I don't know.
Also show the fins at edge of airframe. I would move them 3/4 to 1in from rear edge, so you have some integrity left in the tube for rear centering ring.

I'll look at it later when I have more time, I would certainly comment you have a very detailed file here. As a TAP I find it thorough & well done.

Here's the file for all to see:
